Update 2 (24th May 2010): The beta is back, download it now at the link below.
Update: Well, it was there about four hours ago, but the link no longer works…. I’m pleased to say that it isn’t just me who got all excited. I’ll update this post if the link becomes active again. In the meantime, I did manage to download a copy, so will post my experiences here.
Looks like the beta of BizTalk Server 2010 was released today – three words: Windows 7 Support!
